Plants with more direct UV showed much more purple across all 3 plants. The data shows that the number of terpenes in dried Cannabis flowers increases with a “No Red” light treatment for the final three days of production. Based upon these findings, we feel confident in recommending a spectrum control program that eliminates red light output from fixtures for the final 72 hours of the Cannabis flowering cycle. Terpenes are aromatic compounds that give cannabis some of its most distinct aromas from citrus and berry, to more earthy tones. Many species of plants produce and emit terpenes in a diurnal, or daily cycle that is regulated by a complex web of signaling. There are also many plants that emit terpenes at night to attract nocturnal pollinators (Marinho et al., 2014346). Regardless of when the terpenes are produced or emitted, these processes are often dependent upon cues derived from natural light/dark cycles via a native circadian clock (Dudareva et al., 2004). Several light-sensitive pigments are involved in these processes of production and emission, and the different photoreceptors are dependent upon different wavelengths of light to be activated or deactivated. Emission of terpenes is a process that is entirely dependent upon phytochromes and red/far-red light cues in most plant species (Flores and Doskey, 2015). For example, repeated light/dark phytochrome signaling is necessary for the emission of terpenes in tobacco plants (Roeder et al., 2007). Based on previous findings, we hypothesized that a lack of red light and phytochrome-mediated light/dark signaling on the part of the plant is responsible for an increase in terpene content in cannabis. The plant continues to synthesize terpenes, but a lack of red light to trigger the Pr-Pfr shift results in a lack of terpene emission by the plant, thus causing the terpenes to accumulate in the maturing flowers.

Plant Mol Biol 65: 107-12 Abstract Sound waves technology has been applied to different plants. It has been found that sound waves were at different frequencies, sound pressure levels (SPLs), exposure periods, and distances from the source of sound influence plant growth. Experiments have been conducted in the open field and under greenhouse growing conditions with different levels of audible sound frequencies and sound pressure levels. Sound waves at 1 kHz and 100 dB for 1 h within a distance of 0.20 m could significantly promote the division and cell wall fluidity of callus cells and also significantly enhance the activity of protective enzymes and endogenous hormones. Sound waves stimulation could increase the plant plasma-membrane H+-ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription. Stress-induced genes could switch on under sound stimulation. Sound waves at 0.1–1 kHz and SPL of (70±5) dB for 3 h from plant acoustic frequency technology (PAFT) generator within a distance ranged from 30 to 60 m every other day significantly increased the yield of sweet pepper, cucumber and tomato by 30.05, 37.1 and 13.2%, respectively. Furthermore, the yield of lettuce, spinach, cotton, rice, and wheat were increased by 19.6, 22.7, 11.4, 5.7, and 17.0%, respectively. Sound waves may also strengthen plant immune systems. It has been proved that spider mite, aphids, gray mold, late blight and virus disease of tomatoes in the greenhouses decreased by 6.0, 8.0, 9.0, 11.0, and 8.0%, respectively, and the sheath blight of rice was reduced by 50%. This paper provides an overview of literature for the effects of sound waves on various growth parameters of plant at different growth stages. https://doi.org/10.1016/S2095-3119(13)60492-X

Starting to get there, week10 of flower will start flushing out on Monday till PPM clears

Finally getting them transplanted.

Week 7 12/15-21: Still coasting.. No big changes got the humidity level down.. Buds looking beautiful

Weather was quite good this week, a bit of sun and the temperatures were not too high. The buds are full of trichomes 😎

I payed 55 dollars an eight for the same level of quality, I got 18 eights of top shelf for $10 not including nutrients and supplies, yeah I'm never going back to a dispensary unless I'm traveling. This experience has improved my life in many ways. I got a total of 7.8 ounces from this grow, I'm happy :)

Wow the smell! ghost train smells like a citrusy diesel and the pineapple is getting more of an acidic fruity aroma. they are finally starting to put on some size closing in on the end of week 4 flower, next week i will step up the nutes. I defoliared the bottom 50% of the plant now that it seems to have finished stretching, and removed any big fan leaves blocking the better bud sites. i couldn’t ask for a better first grow so far!

Recomendo

Giving another week didn’t realize these would go so long. I freeze-dried a couple top cola of each pheno to get a better profile on them Terps.

Happy plants 🌿 Happy grower😄👍

One more week and this is the last one before switching to 12/12h, I decided to clean a few more sheets on 15th and I'm sure it will recover very quickly.. Happy growing! ✌️🌱🌿🍁

day 73 I was not ready for all this! 🤣🤣 they literally exploded, even though the buds of El Patron are much thinner than the purple queen I have in my tent, I had to tie them up so that the weight of the flowers didn't break the branches. I have to say that 6 photoperiods are too many for my 1m x 1m x 2m tent. in addition to this I have noticed that they are very hungry. like me and give me some advice. thanks for stopping by, have a nice day and happy cultivation 💚🌳💚🌳💚🌳

She is jumping out the gym sorry couldn't get a shot of her alone my tent is a little crowded shoving her ass into flower tomorrow so excited 😆

She is very oily velvety rub and smells very grapey. Only downside is it's very lanky even some air and silica it's lanky lol. Whatever maybe ill clone and cross it just for its taste.

sehr zufrieden ausgeprägter fruchtiger Geschmack.

Finalizing the grow. Harvest is in one week. One plant needs to cook a bit longer and its not that bad for the others. Fading is normal,Smell and terpene profile is awesome, and the preharvested testbud blew me away. Im drooling :)

Not an overly impressive strain and I would say she was not that hard to grow. If I even grew this one again I would let it go naturally with some LST. Wanted more grape flavours but they don't really come through in the smoke. There's a bit of a sharp fruity smell that's sort of piney with a hint of fuel at the end. The smoke is not too flavourful in my opinion but that just means I didn't grow it well. Super tight nugs so be careful with humidity as stated above. Also she's a bit of a light feeder so be careful with your nutes. As you can see I burnt her tips and over fed her a lot. Not a bad yield though! I've only really smoked the lowers on this one so far so that gave me a bit of a racey high, just slightly racey. I would accredit that to the lowers not being mature enough at chop. The plant is super dense and since I mainlined it the lowers didn't receive enough light. I tried to let the lowers mature more but the plant stopped maturing when I chopped the tops, this caused stress and the plant just shut down basically. Not sure if I would grow Blimburn's GDP again until I grow the real GDP.

12 hours max soaking before directly going into 18ltr pots. Amazing germination speed and rate as always from the guys @ 420FB

Within 2 weeks she will be ready
